Do Oscillations Occur in Inductors When Modifying AM Transmitter Circuits?

[sophiecentaur]

I altered a simple Crystal AM transmitter circuit to meet my needs. I am basically trying to get am modulation without the use of a diode. Does this meet the criteria? Also, the output from audio sources such as iPods are dc biased correct? If I am wrong in thinking this then this whole circuit is doomed from the get go.

I'm afraid that circuit will not work. The ground of the audio input signal is not shown but we assume it is the same ground as the rest of the circuit.
AM stands for Amplitude Modulation. Modulation is a non-linear process and needs a nonlinear element in any circuit. You are connecting the audio input to the battery input - which is low impedance - so the supply volts to the 1MHz unit won't alter and neither will the level of the carrier signal produced. If your 1MHz source produces a carrier with a level proportional to the supply volts (it may or may not) then you need to be altering the supply volts with the audio signal. For low power, you can change the DC supply to the 1MHz oscillator, using a transistor that's driven by the audio and produces a supply voltage that varies in about a mean DC value.
You really should Google Amplitude Modulation Circuits and see the variety of ways in which it is achieved.

PS The best your circuit can do is to Add the two signals together - which is not Modulation
PPS To protect their circuits, most pieces of audio equipment have AC coupled outputs.
